What's the best course of action for a patient with a history of hemorrhoidectomy and fistulotomy, now experiencing chronic pelvic pain and sensation issues, after a second colorectal surgeon found only scar tissue at the fistulotomy site and didn't examine the previous hemorrhoidectomy site?

Recommended Course of Action for Chronic Pelvic Pain After Hemorrhoidectomy and Fistulotomy

You need a comprehensive multidisciplinary pain evaluation with a gastroenterologist experienced in chronic pelvic pain and a psychologist specializing in pain management, combined with consideration of imaging to exclude structural complications at the hemorrhoidectomy site that was not examined. 1

Immediate Next Steps

Obtain Complete Structural Assessment

• Request examination of the hemorrhoidectomy site specifically, as the second surgeon only evaluated the fistulotomy site and found scar tissue. 1
• Hemorrhoidectomy complications occur in approximately 10% of cases and include fissure, abscess, stenosis, and chronic pain syndromes that may not be immediately visible without direct examination. 2
• Consider anoscopy with adequate light source to visualize the hemorrhoidectomy site, as this is the gold standard for evaluating anorectal pathology. 1
• If structural abnormalities are suspected but not visible on examination, pelvic MRI is first-line for characterizing fistulizing disease, scar tissue complications, and soft tissue abnormalities in the surgical field. 3

Address the Chronic Pain Syndrome

• Your pain has likely transitioned from acute post-surgical pain to chronic pelvic pain, which requires fundamentally different management than treating the original surgical condition. 1
• Chronic pelvic pain affects approximately 25% of women worldwide and requires recognition that central sensitization and altered pain processing at the spinal cord and brain level are now maintaining factors. 1, 4
• Screen for risk factors that predict transition to chronic pain: history of other chronic pain conditions, early-life trauma, catastrophizing coping styles, pre-existing anxiety/depression, and negative prior experiences with pain or surgery. 1

Multidisciplinary Pain Management Algorithm

Pharmacologic Foundation

• Start low-dose tricyclic antidepressants or serotonin-norepinephrine reuptake inhibitors (SNRIs) as baseline therapy for neuropathic and chronic post-surgical pain. 1
• These adjuvant analgesics target central sensitization mechanisms and altered descending pain modulation from brainstem nuclei. 1
• If opioids are being considered, screen for aberrant use risk with validated tools (SOAPP-R or ORT), use the lowest dose possible, and reevaluate regularly. 1
• Avoid prolonged use of potent topical corticosteroids, though short-term use may help perianal irritation. 1

Brain-Gut Behavioral Therapies

• Referral to a psychologist experienced in chronic pain management is essential, not optional, as psychological factors are always present whether as antecedent or consequence of chronic pain. 1, 5
• Instruction in breathing techniques should be initiated immediately by your gastroenterologist. 1
• Cognitive behavioral therapy is indicated for patients with insight into how thoughts, feelings, and behaviors relate to pain. 1
• Hypnotherapy is effective for visceral hypersensitivity and somatic symptoms if delivered by certified clinical providers without severe PTSD contraindications. 1

Physical and Interventional Approaches

• Physical therapy and myofascial trigger point injection therapy may address pelvic floor muscle dysfunction and myofascial pain components. 1, 5
• Self-management strategies and neuromodulation techniques should be incorporated. 1

Critical Pitfalls to Avoid

Don't Assume All Pain is Scar Tissue

• Scar tissue alone does not explain chronic pain with sensation changes—this suggests neuropathic pain from nerve injury or central sensitization. 1
• The presence of muscle fibers in hemorrhoidectomy specimens is normal and does not indicate surgical error. 2
• Approximately 20% of patients with chronic pelvic pain have non-gynecologic causes including gastrointestinal and musculoskeletal origins. 3, 4

Recognize Hemorrhoidectomy Was Likely Inappropriate First-Line

• Hemorrhoidectomy should only be performed for failure of medical and nonoperative therapy, symptomatic third/fourth-degree hemorrhoids, or mixed internal/external hemorrhoids—not as first-line treatment. 1
• Nonoperative techniques (rubber band ligation, sclerotherapy, infrared coagulation) are appropriate for second and third-degree hemorrhoids with lower complication rates. 1
• Standard hemorrhoidectomy with proper indication is safe, but complications occur in 10% of cases, and inappropriate indication increases risk. 2

Address the Elephant in the Room

• The second surgeon's reluctance to examine the hemorrhoidectomy site and lack of recommendations suggests concern about the appropriateness of the initial surgery. 1
• You have the right to complete medical evaluation regardless of medicolegal concerns—request a third opinion from a colorectal surgeon at an academic center with no prior relationship to either surgeon. 1
• Document all symptoms, obtain copies of all operative reports, and maintain detailed pain diaries with 0-10 numeric rating scales. 1

Goals of Management

• The primary goals are increasing comfort, maximizing function, and improving quality of life—not eliminating pain entirely, which may be unrealistic at this stage. 1
• With comprehensive application of available interventions, approximately 80% of patients with chronic pelvic pain report reduction to tolerable levels maintained at 3-year follow-up. 5
• However, 20% experience unsatisfactory results and require integrated pain center referral with psychological support and antidepressant medication. 5
